While flea markets and estate sales are good places to find some local scouting memorabilia, you probably won’t find a Camp Naish sign like this in one of those venues:
While working as a volunteer ranger at Camp Naish in the 1990s, my dad saved this from the dumpster/scrap pile when the covered information board/bench structure was removed from the end of the Central Camp parking lot. The base of the structure had rotted, so the whole thing was taken down. He happened to be at the right place at the right time and saved it from destruction. It is about 8.5 feet long and has the ubiquitous brown and yellow paint scheme from Camp Naish.
This hangs in what we playfully call “the Museum.” Also pictured is a display of Scouting memorabilia including my Tamegonit Lodge collection (at far right), my dad’s Eagle Scout certificate and medal, my brother’s Eagle Scout medal and my Eagle Scout medal, and my dad’s troop’s summer camp picture at Camp Naish from 1960.
This makes me think of the old sign at the entrance to Camp Naish (I think Bartle had one too) that said something to the effect of., “SLOW DOWN. One boy’s life is worth all your time.”
Did that make it to the burn pile or is it hanging in your basement?

I remember that sign, and the “slow down” sign.
I was out at Camp Naish just a couple of weeks ago, and was amazed at the changes. I haven’t been out there for about 15 years….
Found out that I miss it too……
The sign you speak of is still in use at Peircing Arrow at bartle. I saw it this past summer.
